<h1>Sketcher</h1>
<p><span style="font-size: 12pt;"><font size=3 style="font-size:12pt;"><b style="font-weight: bold;"><img src="i_blue.jpg" x-maintain-ratio="TRUE" x-save-file="TRUE" x-save-method="compute-relative" width="30px" height="30px" border="0" class="img_whs1"></b></font></span>Sketcher allows to create curves of 2 types: line
segment and arc. The
curve is created from the current point (center of coordinates when the
sketcher is started). The
end of the curve is defined by means of "destination", which
can be a destination point (for segment only) or destination direction
coupled with length of a segment or angle and radius of an arc.</p>
<p> </p>
<p>Sketcher is able to create planar curves only. Therefore, it is necessary
to select a working plane before starting a sketch (by default, XOY plane
is used). Sketcher creates curves lying in the current working plane (New
Entity -> Basic -> Working Plane).</p>
